JOHN FOX, OF WOLSELEY, SASKATCHEVTAN, CANADA.

GRAIN-PICKLER.

Specification of Letters Patent.

Patented Mar. 6, 1917.

Application filed July 3, 1915. Serial m. 35,038.

To all whom it may concern:

Be it known that I, J OHN Fox, a subject of the King of Great Britain,residing at Volseley, in the Province of Saskatchewan and Dominion ofCanada, have invented certain new and useful Improvements inGrain-Picklers; and I do hereby declare the following to be afull,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention is a grain-pickling appa ratus for use in destroying thegerms of smut by thoroughly sprinkling the grain and mixing the samewith a suitable germ destroying solution, the object of the inventionbeing to provide improved apparatus of this kind which is simple inconstruction and which is thoroughly efiicient in operation.

The invention consists in the construction, combination and arrangementof devices hereinafter described and claimed.

In the accompanying drawings:

Figure 1 is a vertical sectional view of a grain pickling apparatusconstructed in accordance with my invention.

Fig. 2 is a plan of the same.

Fig. 3 is a detail sectional view through the spout and baflies andillustrating a modified form of the mixing spout.

Fig. 4 is a detail sectional view of the spout and its associated parts,on a plane at right angles to that of Fig. 1.

Fig. 5 is a detail vertical sectional view on the plane indicated by theline 5-5 of Fig. 1.

Fig. 6 is a sectional. view showing another modified construction of themixing spout and its connections.

Fig. 7 is a sectional view on the line 7-7 of Fig. 1.

In the embodiment of my invention here shown a supporting frame 1 isprovided which comprises a pair of inverted U-shaped members each ofwhich has a horizontal intermediate portion 2 and downturned supportinglegs 3. The legs of the said members are connected together in spacedrelation by crossed braces 4. A tank 5 to contain a suitable germdestroying solution is arranged on one end of the supporting frame andis secured thereto by means of a pair of hook rods 6, which have theirupper ends connected over the upperedge of the wall of the tank andtheir lower ends pass through a cross bar 7 under the parts 2 of theframe and provided with clamping nuts 8.

Near the opposite end of the frame is an inverted frusto-conical hopper9, which has an opening 10 at its lower end and has its lower endsecured as by means of rivets 11 in the uppervoutwardly flared andenlarged end 12 of the vertically arranged mixing spent 13. Said spoutis arranged in an opening in a cross plate 14 which connects the parts 2of the frame. A pipe 15 leads from the bottom of the tank 5 to the upperportion of the mixing spout, extends across the mixing spout and isprovided in that part which extends across the mixing spout withperforations 16. A controlling valve 17 is also provided for said spout.In the lower end of the hopper is a conical valve 18 which may be raisedand lowered by means of a rod 19 and a handled nut 20 which engages thethreaded upper portion of said rod, said rod passing and being free toslide vertically through a central opening in the top 21 of the hopper.

Mixing devices are arranged in the spout 13 and in the form of theinvention shown in Fig. 1 comprise spreading cones 22 and invertedfrusto-conical concentrators 23, each spreading cone having its basearranged in the center of and spaced from the upper end of one of theconcentrators and connected thereto by radially arranged wires 2-1.These mixing devices are arranged one above another, with the upper endof each cone excepting the uppermost in the center of the lower end ofone of the concentrators and said mixing devices I are connectedtogether by wires 25 which form a bail at the upper end of which is ahook 26 which engages over the pipe 15 and hence suspends the mixingdevices in the spout. The greatest diameter of the concentrators ispractically equal to the innor diameter of the-mixing spout so that themixing devices are arranged closely in the spout.

In the operation of my invention the grain to be pickled is placed inthe hopper U and the tank 5 having been supplied with solution and thevalve 17 opened to the desired extent the valve 18 is then slightlyraised to permit the flow of grain from the hopper into the mixingspout. As the grain descends through the mixing spout.

it is sprinkled with the solution from the lorperforations 16. The grainas it descends is first spread by one of the cones 22 and thenconcentrated by one of the concentrators 23 and hence the grain isthoroughly mixed and all of the grains are effectually wetted or pickledby the solution, thus killing the smut germs the pickled grain beingfinally discharged at the lower end of the spout through the lowermostconcentrator.

In Fig. 3 I show a modification. in which the mixing spout 13 isprovidedwith oppositely inclined deflectors or baffles 27-28 between whichopenings 29 are formed. It will be understood that as the grain passesdown through this spout it is thoroughly mixed and is also subjected tothe action of the solution discharged through the perforations of thepipe 15.

In Fig. (3 I show another modified con struotion in which a mixing wormor screw 30 is arranged in the spout 13.

Having thus described my invention I claim:

1. A grain pickling apparatus including a spout, and a unit of mixingdevices rcmovably mounted in the spout, said unit comprising a vertical.rod, a plurality of cones having their apices connected to said rod andarranged in superposed relation, a plurality of Wires arranged upon thebase of said cones and extending radially therefrom, frusto-conicalconcentrators having their larger ends secured to the radial wires,their lower ends positioned beneath the base of the cones and extendingbelow the apex of one of the cones, and means for removably supportingthe mixing devices in the spout.

2. A grain pickling apparatus including a hopper, a spout having one endflared and h surrounding the mouth of tl1Bl101)P6l,2lvalve verticallymovable within the hopper closing the spent, a unit of mixing devicesremow ably arranged in said spout, means extending through the upper endof the spout adjacent its point of connection with the hopper forremombly supporting the mix-- ing devices in the spout, said mixing devices comprising cones arranged in superposed relation and held atspaced distances apart and frusto-conical concentrators secured to thelarger ends of the cones for thoroughly mixing the grain passing throughthe spout.

In testimony whereof I allix my signature in presence of two witnesses.
